The object of my invention is to produce a rugged and efficient clothes wringer, the parts of which may be readily fabricated and assembled at low cost, the construction being such that the upper roll may be readily associated with or disassociated from the lower roll and such that the upper roll may be quickly relieved from pressure, from either side of the device, by a comparatively small pressure applied by the operator in a direction toward the structure.

'lhe accompanying drawings illustrate my invention Fig. 1 is a. side elevation in partial axial vertical section of an embodiment of my invention;

Fig. 2 is an end elevation;

Fig. 3 is a vertical section on line 3-3 of Fig. 1;

Fig. 4 is a vertical section on line 4-4 of Fig. 1;

Fig. 5 is an end elevation of the upper roll unit;

Fig. 6 is a plan of one end of the lower roll unit; f

Fig. 7 is a fragmentary section on the line 7 7 of Fig. 1;

Fig. 8 is a medial transverse section of a modification;

Fig. 9 is a section, similar to Fig. 3, of a modification; and

Fig. 10 is a fragmentary perspective of the drain pan receiving means.

ln the drawings, 10 indicates a base formed preferably of pressed sheet metal and comprisirgF vertical standards 11, 11, each channeled to receive, guide, and support bearing blocks 12 in which is ournaled the shaft 13 of the lower roll 14.

The standards 11, 11 are spaced apart a desired distance and are connected by a bib plate 15 preferably an integral part of the.

base, one on each side*l The inner ends of plates 15 are connected and vertically distorted to form a trough 16 within which the lower roll 14 lies.

Mounted in the base on each side of the middle axial vertical plane are spring torsion bars 19, 19, each provided at its middle with a nonsrotative U-shaped bracket 20.

Each torsion bar 19 is rotatably supported in a pair of ears 21, 21 flanking the arms of the bracket and bracket 20 is adjustably held against rotation in one direction by a set screw 22. The torsion springs may be of any one of a number of forms but l have found in practice that each may be very satisfactorily made of a polygonal rod of steel, as indicated in the drawings, readily obtainable. in the market at low cost.

Non-rotatively secured to the free end of each spring 19 is an arm 25 )rovided at its outer end with a pin 26 projecting axially of the rolls. The arms 25 at each end of the structure are projected toward each other and their pins 26 lie in a horizontal slot 27 formed in the lower end of a vertically mov able plate 28 guided for vertical sliding in the. standards 11 by pins 29 carried by the base and projecting through vertical slots 30 in plate 28. rlhis plate is niedially slotted at 31 to permit the passage therethrough of the shaft 13 of the lower roll. Plate 28 near its upper edge carries an inwardly projecting pin 32 upon which is journaled a roller Slidably mounted in, and vertically removable from, standards 11 is a yoke 35, each depending arm of which carries an outwardly projecting shouldered pin 36 upon which is pivoted a latch arm 37, the lower end of which is outturned to form a linger 38 adapted to take under the adjacent roller 33, said finger in its upper surface being provided with a shallow notch 39 serving to position the latch 37 in vertical position. The upper ends of the two latches 37 are anchored in the hollow head 40 which forms a cap over the upper ends of the standards 11 and a iinishing cross head which the operator may readily grasp to manipulate the latches 37.

Vertically slidably mounted in the ways carried by yoke 35, at each end ofthe' yoke, is a bearing block 46 in which is journaled one end of shaft 47 of the upper roll 48. Each bearing block 46 is adjustable in yoke 35 by means of an adjusting screw 49.

lVhen the parts are in the positions shown in full lines in the drawings, the cap 40 lies vertically over and covers the rolls and the upper open ends of tlie standards 11, and fingers 38 of latches 37 lie beneath i'ollers 33 and have pulled plates 28 upwardly, swinging the adjacent ends of arms 25 upwardly and torsioiially stressing the springs 19 so that the upper roll 48 is yieldingly urged upon the lower roll 14.

The operator, from either side of the inzicliine, by a blow upon cap 40, may swing latches 37 upon their pivot pins 36 to withdraw fingers 38 from beneath rollers 33, thereby releasing the pressure upon the upper roll 48, whereupon the upper roll structure may be withdrawn upwardly from the base, guides 45 and yoke 35 sliding upwardly in the standards 11.

To reassemble the parts, latches 37 aie tilted, relatively to yoke 35, to the position shown in dotted. lines in Fig. 3, whereupon yoke 35 and its associated parts may be projected downwardly into standards 11 until roll 48 rests upon roll 14, at which time fingers 38 have descended to a position Where, upon swinging latches 37 upon their pivot pins 36, the fingers 38 may be projected beneath the rollers 33 to draw said rollers and their associated plates 28 upwardly to restress the torsion springs.

By utilizing torsion springs of the character illustrated in the drawings the cost of production is very greatly reduced and it is possible to produce a wringer, the overall height of which is substantially less than has been heretofore commercially practical, without sacrifice of sutiicient leverages to permit establishment and Arelease of roll pressures by the exertion of a comparatively small amount of force well within the physical capacity of the average woman operator.

It will be noted that the opposite ends of each spring 19 function independently and, of course, independent springs might be provided without departing from my invention.

It will also be readily understood that a single torsional spring at each end of the structure, if sufficiently strong, would be sufficient but I believe that the arrangement shown is more satisfactory because ot the possible balancing of stresses.

Referring to Fig. 8, the bibs 15 have down turned inner edges 15l to which are welded the upper edges of the trough piece 16.

Instead of notchiiig the fingers 38 at 39, as shown in Fig. 3. the notches may be omitted and the head 40 normally held in medial position by a spring 60 the ends of which are retained under the inturned edges 40 of head 40 and the middle ot' which is distorted to form a pocket G1 (flanked or defined by rounded ribs 62, 62) adapted to yieldingly receive and retain the middle of yoke The reversible drain pan 70 is removably bolted, by bolts 71, to brackets 72 which are conveniently rivet-pivoted to ears 73 of the trough piece 16. vPan 70 is provided with a segment arm 74 having teeth which mesh with the teeth 75 of a split sleeve 7G frictionally clamped on the shaft of the lower roll by a spring ring, 77.

Fig. 9 shows a modified connection hctween latch arm 37 and the springs 19. In this construction the vertically movable plate 28 (slotted at 31 to receive the lower shaft 13) is slidable in guides 63 and is provided with pins 26 which take into slots 27 foi-ined in the levers 25 caii'ied by springs 19. Plate 28 is provided with a ioller 33 as in the form shown in Figs. 1 and 3.

Each lever 25 is provided with an arm 25 carryingan adjustable temper screw normally engaging the base frame so as to prevent roller 33 from being moved below the range of movement of linger 38. By means of this construction springs 19 may be placed under any desired initial stress by -adjustment ot temper screws 22 without carrying rollers 33 out of range of engagement of fingers 38.
